Hot-press forming die for panel of large cabinet air conditioner

Abstract

The invention discloses a hot-press forming die for a panel of a large cabinet air conditioner. The hot-press forming die for the panel of the large cabinet air conditioner comprises an upper die baseand a lower die base, and an external heating plate is arranged between the upper die base and the lower die base; two punches which are oppositely spaced front and back are arranged on the bottom face of the upper die base, a forming die core is arranged on the top face of the lower die base, and positioning pins are arranged on the top face of the forming die core; lower stripping plates are respectively stacked on the portions, located outside the front side and the rear side of the forming die core, of the top surface of the lower die base, and first lifting driving devices for respectively driving the two lower stripping plates to move up and down are arranged on the lower die base; and material pressing plates are stacked on the lower stripping plates, and second lifting driving devices for driving the material pressing plates to move downwards are installed on the lower die base. Compared with the prior art, the shape of the panel of the large cabinet air conditioner is formedin a hot press molding mode, the manufacturing process is simple and reliable, the first pass yield of finished products is high and can reach 90%, mass production can be achieved, and the problem that mass production cannot be achieved due to the fact that a pouring gate and a mark exist in a traditional injection molding mode is solved.

Description

technical field [0001] The invention relates to a molding die for a panel of an electronic product, in particular to a hot-pressing molding die for a panel of a large air-conditioning cabinet. Background technique [0002] As we all know, vertical cabinet air conditioners are bulky and are usually placed in the corner of the living room. The air conditioner cabinets we saw in the past few years are basically square! With the rapid development of the country's economy, people's living conditions are getting better and better, and everyone's aesthetics for the appearance of air-conditioning cabinets has gradually improved. In recent years, air conditioner manufacturers have also launched some cylindrical cabinet products. This cylindrical cabinet not only has improved functions, but also has diversified colors and a very good-looking appearance. The panels of the existing cylindrical cabinet machines are generally plastic panels, and some patterns are printed on the back of t...

AI Technical Summary

Problems solved by technology

The panels of the existing cylindrical cabinet machines are generally plastic panels, and some patterns are printed on the back of the plastic panels. For high-quality plastic products, it is the light transmittance of the plastic panel that makes the quality requirements of the surface of the material products very strict, and there must be no air marks, silver marks, bubbles, whitening, halo, yellowing, black spots, and vibration marks. , poor gloss and other defects; while the size of the panel of the cylindrical cabinet machine is 1791.5X361.5X114mm, the thickness is 1.5mm; such a large fully transparent product and the wall thickness is only 1.5mm, if the injection molding process is used, the above plastic panel Defects are difficult to avoid completely, resulting in too low a product yield rate and cannot be mass-produced; moreover, the gate of the product and the imprint of the ejection structure on the back cannot be hidden, so the existing large-scale air-conditioning panels cannot be mass-produced
